A history of punctuation!
Who doesn’t want to know where the octothorpe originated before
the Internet hijacked it as the hashtag? And the ampersand.
Everyone loves that little piece of punctuation that seems
impossible to write perfectly by hand but has persisted
still against all odds.

And for reading fun, I just think you should read all of DOGZPLOT.
With stories shorter than 200 words, you can read dozens at a time and
get lost in a wonderful world of itty bitty fiction. A minor
sidenote: I’m in there somewhere. Happy reading!
